Explosion-Proof Borosilicate Glass Lens for Mining Lamp and Hazardous Area Lighting
1. Material Composition:
Reinforced Borosilicate Glass: High-purity material (Schott B270 or equivalent) with tempered strengthening for impact resistance.
Explosion-Proof Encapsulation: Stainless steel or brass housing with flame-arresting grooves and tempered sealing gaskets.
2. Key Properties:
Explosion Resistance: Certified for ATEX/IECEx Zone 1 & 2 (gas) and Zone 21 & 22 (dust) hazardous environments.
Thermal Shock Tolerance: Withstands ΔT > 150°C (e.g., rapid cooling from 300°C to room temperature).
Mechanical Strength: IK10 impact rating and 6.5 Mohs hardness to resist abrasion and flying debris.
Chemical Inertness: Resists corrosion from acids, alkalis, and solvents (excluding HF).
3. Core Functions:
Flame Containment: Prevents internal sparks or explosions from igniting external flammable atmospheres.
Optical Clarity: >92% light transmission with minimal distortion for uniform illumination in low-visibility environments.
Environmental Sealing: IP67-rated protection against dust, moisture, and corrosive gases.
4. Applications:
Mining Lamps: Cap lamps, tunnel lighting, and explosion-proof handheld lamps for underground coal mines.
Oil & Gas Facilities: Hazardous area lighting for refineries, drilling platforms, and petrochemical plants.
Chemical Processing: Lighting for explosive atmosphere workshops, storage areas, and reaction chambers.
Grain & Powder Industries: Dust-proof lighting for silos, mills, and pharmaceutical production zones.
